What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in Parent Rated Social Responsiveness Scale, 2nd Edition (SRS-2) T-Score After Treatment.	Social Responsiveness Scale, 2nd Edition (SRS) scores measure social abilities with lower scores meaning better social abilities. (T-Score Range: 37- above 90 )	Baseline, 12 Weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in Parent Rated Repetitive Behavior Scale Revised (RBS-R) Scores During Treatment.	Higher scores on the Repetitive Behavior Scale- Revised mean higher levels of repetitive and restricted behaviors. (Raw Score Total Range: 0 - 129)	Baseline, 12 Weeks
Change From Baseline in Parent Rated Stanford Social Dimension Scale (SSDS) Scores During Treatment.	Higher Scores on the Stanford Social Dimension Scale mean better social functioning and lower scores mean worse social functioning (Range: 58-290).	Baseline, 12 Weeks
Change From Baseline in Parent Rated Vineland Adaptive Behavior Scale- 3 (VABS-3) Scores During Treatment.		Baseline, 12 Weeks
Change From Baseline in Parent Rated Short Sensory Profile Questionnaire (SSPQ) Scores During Treatment.		Baseline, 12 Weeks
Change From Baseline in Parent Rated General Self Efficacy Scale (GSES) Scores During Treatment.		Baseline, 12 Weeks
